1 AC, or alternating current means the electrical current is alternating directions in a repetitive pattern.  AC is created by generators in power plants, and other sources. This AC current is delivered to our homes and businesses by the power lines we see everywhere.
Current. The transfer of charge (i.e. moving charge) is called current. More specifically electric current is the rate of flow of charge i.e. the amount of charge passing a given point in a circuit each second.The unit of current is the Ampere (A) and 1 Amp is therefore 1 Coulomb of charge passing each second.1 A = 1 C / s.ore specifically electric current is the rate of flow of charge i.e. the amount of charge passing a given point in a circuit each second.
